Letters Patent No. 114,089, dated April 25, 1871.

IMPROVEMENT IN COOPERS CROZE.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern:

Be it known that we, JOSEPH F. APPLEGA'TE and GASPAR FEIOCK, of NewAlbany, in the county o1 Floyd and in the'State of Indiana, haveinvented certain new and useful Improvements in Cooper- Croze; and dohereby declare that the following is 'a full, clear, and exactdescription thereof, reference being had to the accompanying drawing andto the letters of reference marked thereon making a part of thisspecification.

The nature of our invention consists in certain improvements upon theCoopers cro'ze for which Letters Patent were granted to Applegate,Jacobs 85 Roby February 2S, 1871, and which will be hereinafter morefully set forth.

In order to enable others skilled in the art to which our inventionappertains to make and use the same, we will now proceed to describe itsconstruction and operation, referring to the annexed d'rawing,'in which-Figure 1 is a side view, and

Figure 2 is a bottom View.

A represents the plate, and

B the head-block, with its V-shaped rib a.

In this case we attach the head-block to the plate by means of bolts andnuts, and interpose between them a wooden raising-block, b, of anydesired thickness, so as to use the same croze or toolfor any sizedchime or barrel, from the shortest to the longest.

On the inner side of the head-block B is a permanent bar, C,throughwhich the screw D passes for fastening the knife; but instead ofthe metal block fastened by two screws, as in the patent above referredto, we use a small wooden block, el, which tits within the V-shaped bitor knife E, and against which the screw D works, thereby perfectlyfastening the bit, and `at the same time preventing any shavings frompassing in between the bit and the block, which was almost always thedifficulty in the former case.

The opening in front of head-block is also made larger to allow chips orshaviugs to come out freely, and the ends of the bead or rib a arerounded, as shown at 1', t', lig. 2.

Having thus fully described our invention,

What we claim as new, and desire to secure by Letters Patent, is-- 1.The head-block -B, with cross-bar C, in combination with screw D, woodenblock d, and bit E, all constructed and arranged substantially, as andfor the Jpurposes herein set forth.

2. The combination of the head-block B with crossbar C, screw D, woodenblock tl, bit E, raising-block b, and plate A, all constructed andarranged substantially as and for the purposes herein set forth.

In testimony that we claim the. foregoing we have hereunto set our handsthis 18th day of February, 1871.
